Eon TBL tech talk tomorrow

[Jobbo]

I noticed Dep/TBL (Andreas Fredriksson) is giving a talk at the below link tomorrow, could be interesting to some people here.

A touch expensive for me. $59 USD for a virtual ticket for the two days. Am sure it'll be a great talk, but I can wait for it to be put online if it is.

“Is Handmade Seattle live-streamed?
Yes. We stream the entire conference for free on this website and Twitch as backup. Official discussions, however, are gated behind a private chat server: you’ll need a ticket for that.”

Says chat is gated. So watching live is free.

Thanks for the heads up @Jobbo, apologies for not digging deeper.

It's right now btw. Twitch link (in case other one isn't working) https://www.twitch.tv/abnercoimbre
EDIT: Stream is on, but don't know when the relevant part will be..
EDIT2: Starting right now

[paraj]

The talk is available here (at least for now): https://www.twitch.tv/videos/1978214964 (starting from 1:31:30).

Focus was (understandably) on lessons for game devs, but was interesting enough. There is nothing new amiga-wise if you've read the blog series (https://tbl.nu/posts/) though.

What an amazing talk!!

[copse]

I agree with @paraj. The talk is more of a higher level overview than the blog series. I recommend just reading the blog series and skipping the talk.

Does anyone know if any of their changes ended up back in WinUAE? The memory protection, etc.

[Jobbo]

I think they customized fs-use.

I like the memory protection idea though. Would be a great addition to Bartman’s tool chain!

[paraj]

I think all (or most) of the custom features they use are possible in stock WinUAE. Looked into it after reading the blog series while working on whdload slave for the demo.

UAECMD macro
.call\@:
        pea     0.w
        move.l  a0,-(sp)        ; output (not used)
        pea     .cmdend\@-.cmd\@
        pea     .cmd\@(pc)
        pea     -1.w
        pea     82.w

.cmd\@: dc.b    \1
        dc.b    0
.cmdend\@:
        even
.done\@:
        endm

Examples:

        ; Trap writes to first 512K of chip ram
        UAECMD 'dbg "w 0 0 $80000 w"'
        ; Enter debugger
        UAECMD 'AKS_ENTERDEBUGGER 1'
        ; Enable warp mode
        UAECMD  'AKS_WARP 1'
        ; Disable warp mode
        UAECMD 'AKS_WARP -1'

Don't use it for evil or complain too much to Toni lest it be removed/changed

Note that you need the UAE boot rom to be enabled (happens when e.g. a HD is attached). Not sure what the easiest way to get it enabled is otherwise.
